Ron later appeared in The Love Boat, The A-Team, CHiPS, Murder, She Wrote and One Life to Live, but he was always best-known for his beloved character in Kotter. The actor admitted this was both a blessing and a curse.

"While I loved him — I really loved him — I didn't want to do him forever," he once said.

Though probably frustrating, Ron seemed to keep a sense of humor about his Kotter character, appearing in an episode of Celebrity Boxing in 2002 along with Dustin Diamond, who played Screech Powers (a kind of '90s version of Horshack) on Saved By the Bell.
